| how do i have the water pump impeller and intake hose checked anyway ???? well i have the k&n cold air intake system i figured that would give it more air flow and help the cooling down part..... and on that article on the air dam are u suggesting i should make a air dam for it??? |

supbud;
To check the intake hose -watch it while someone suddenly revs up the engine. BE Careful! If it collapses it’s bad.
The impeller is a flow test - you drain and save the coolant mix, remove thermostat replace the housing and then with cold water in the system aim the output hose out from under the hood. At idle it should have very good flow. Turn the engine off before the radiator is emptied.
... I made my air dam for my old Jeep from scrap aluminum. Front ground effect plastic parts should be available from J.C Whitney.
Here's another thought... If you've got an automatic!
The job of the add on Transmission cooler is to help dissipate heat but why put this additional heat in front of the radiator and in front of the air conditioning condenser?
Most modern vehicles are operating at temperatures over two hundred degrees and are being taxed to handle the added heat of transmissions under a heavy load. So in many cases the oil is going back into the transmission too hot. The life of the automatic transmission relies on the life of the oil and the additives in the oil and heat shortens the life of the oil and the additives in them.
... Add on coolers should be used as pre-coolers in series with the cooling core in the radiator. An after-cooler would cool the transmission oil better but still put too much heat into the engine coolant as well as be too cool in the wcooler in the hot out-put line between the transmission and radiator and it and it will be a pre-cooler. I used a clear piece of hose connected to the in and out cooling lines to find out which was which. After connecting the clear hose have someone start the engine while you watch to see which way the bubbles flow to tell which line is which.
The Pre Cooler will reduce the frequency of needed automatic transmission fluid changes.
TIP: I have noticed many stock cooling lines need to be insulated from headers and pipes.... I shielded my cooling lines with a scrap piece of aluminum.
... First look for a mounting place away from the exhaust system. Look for mounting places under the bed. The cooler will dissipate a lot of heat even without much air flow because the oil will be VERY hot when the transmission is under a load. For HD towing a small 12 volt fan could be installed.
The Pre Cooler will reduce the frequency of needed automatic transmission fluid changes.
... I mounted a pre-cooler to the top of the front skid shield (passenger side behind the radiator) on my wife’s V-8 ‘99 Grand Cherokee. I noticed later there was a nice safe place under the body behind the drivers seat.
Have a good one while you can still laugh about it.. Don S..
There was a time when some people got rich buy providing a better product at a lower price.
Now they get rich by ripping us off and paying off the politicians. Can you spell DEREGULATION
